ICE-CUTTING MACHINE.

Application filed April 30.

. To all whom it may concern Be it known that I, EDWARD B. HANSON, acitizen of the United States, residing at Buxton, in the county of Yorkand State of Maine, have invented certain new and useful Improvements inIce-Cutting Machines;

and I do hereby declare the following to be improvements in apparatusfor cutting ice and comprises a simple and efiicient apparatus of thisnature having various details of construction and combinations andarrangements of parts which will be hereinafter fully described, shownin the accompanying drawings and then specifically defined in theappended claims.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of the apparatus. Fig. 2 is a top planview. Fig. 3 is a vertical sectional view on line 33 of Fig. 2, showingparts in elevation. Fig. 4 is a sectional view on line H of Fig. 2. Fig.5

- is a section on line 55 of Fig. 4:. Fig. 6

is a view in elevation of the opposite side of machine shown in Flg. 1,and Fig. 7 1s a detail view showing means of securing pulley G to flywheel.

Reference now being had to the details of the drawings by letter, Adesignates the runners of the apparatus held parallel to each other bythe cross-pieces A. Pivotally mounted upon the shaft B are the beams Bwhich, at their outer ends, carry the arbor C upon which the saw C isfixed, said frame being adapted to have a vertical swinging movement.Pivotally connected to a pin D upon one of said beams 1;" is a link Dwhich at D is pivotally connected to an arm D which in turn is fixed toa shaft E journaled in bearings in the standards E. The shaft ,E hasfixed thereto a second arm E which has pivotal connection through themedium of the link E with one arm of the angle lever E which latter ispivotally mounted upon a pin E fixed to one of the runners.

An operating lever, designated by letter B", is pivotally connected to apin E upon the runner and a rod E pivotally connects Specification ofLetters Patent.

one arm of the angle lever with the lever E shown clearly in Fig. 1 ofthe drawings. A hand-operated pawl E is mounted upon the lever E andadapted to engage notches in the segment 15 for the purpose of holdingthe saw at different elevations.

Upon reference to Fig. 2 of the drawings, it will be noted that adriving pulley F is fixed to the shaft B and has belted connection Fwith a pulley F fixed to the saw arbor. An idler pulley F is journaledupon the arbor and from which the belt may be shifted by means of thepivotal lever F.

An engine G is mounted upon a suitable base which is supported by therunner and affords means for supplying power to drive the saw and alsoto The pulley Gr secured to the arms of the fly wheel by bolts G has abelted connection G with a pulley H which is fixed to the shaft B,affording means for driving the latter.

propel the apparatus.

The means for propelling the apparatus fixed to the shaft J journaled insuitable bearings in the rack bars J 2 movable between guides J andpinions J which are fixed to the shaft J journaled in the runners.

The means for raising and lowering the spur wheels consist of the leverL which is fixed to the shaft K and carries a hand-operated pawl Ladapted to engage the teeth of the segment L A rod L pivotally connectsthe lever L with the lever L which is fixed to the shaft J affordingmeans whereby, as the said lever is moved in one direction or the other,the two sets of spur wheels may be raised so that their lower portionswill be above the bottom of the runners or lowered so that they willengage with the ice.

Fixed to the shaft 1 is a sprocket wheel I about which a sprocket chainI passes and which latter also passes about a sprocket wheel I fixed tothe shaft I. Also fixed to the shaft I are the twosprocket wheels N andN and a sprocket chain N passes about the sprocket wheel N and asprocket wheel N which is fixed to the shaft J. A sprocket chain Npasses about the sprocket wheel N and a sprocket wheel N which is fixedto the shaft 0 journaled in suitable bearings supported by the runners.

Two shafts, designated respectively by letters Q; and Q, are journaledat corresponding ends in hearings in one of the runners and have theiropposite ends journaled in an adjustable bearing box It" which ismounted upon the other of said runners. A pulley wheel Q is fixed to theshaft Q and a similar pulley Q is fastened to the shaft Q. A belt Ppasses about a pulley P upon the shaft 15 and also about the pulley Qalso a belt 1 passes about the pulley 1 upon the shaft B and said pulleyQ. Fixed to the shaft Q is a frictional driving pulley 1t and a similarpulley R is fastened to the shaft Q. Said friction pulleys are adaptedto have a movement in contact with or away from the friction pulley Twhich is fixed to the shaft 0. A. lever S is pivotally mounted upon astandard S and has a hand-operated pawl S for engagement with the teethof the rack S and a rod S pivoted at one end to the lower end of thelever S and its other end is fastened to the movable boxing R, servingas means for throwing the friction wheels R and R into or out ofengagement with the circumference of the fricticnally driven wheel T.

Means for marking the ice to be cut consists of the two blades and Vwhich are fastened to the bars and which blades are adapted to have alateral adjustment upon the rods W and W respectively, the outer ends ofwhich are supported by the brace bars W while 'the inner ends are hingedto the runner as at so as to allow the blades W to be raised or loweredso that they may come in or out of contact with the ice when the leversY and Y are actuated.

Standards X and X rise from one of the runners and upon the latter ofsaid standards X is a pulley X about which a cable X passes and which isfastened at one end to an eye l' -upon one of said marking blades W andat the other end to one end of the pivotal lever Y mounted upon thepivot pin Y. A second lever Y pivoted upon a pin Y has its inner endextending underneath the adjacent end of the lever Y, affording meanswhereby, as the lever Y tilts, the lever Y will also tilt. Mounted uponthe standard X is a pulley X about which a cable V passes and which issecured at one end to the lever Y and its other end to an eye V fastenedto the blade N. end of the lever Y has a foot tread W, affording meanswhereby an operator by depressing upon said foot tread may cause the twolevers Y and Y to tilt and, through their cable connections with themarking blades, cause the same to be raised. I

The operation of my invention will be readily understood and is asfollows: By the manipulation of the lever L, the spur One wheels may bethrown down to project below the bottoms of the runners. Power beingsupplied by the engine will drive the saw arbor, the saw being adaptedto be "aised and lowered through the medium of the lever G andconnections with said arbor, thus regulating the depth at which it isdesired to have the saw cut through the ice. Power is applied to theshaft Q, and Q through the belted connections shown, thus rotating thefriction driving wheels. A swinging movement of the lever S will causethe friction driving pulleys R and R to be moved in frictional contactwith the pulley T, thereby causing the latter to rotate and, through thebelted sprocket wheel and chain connections, cause the spur wheels torotate and engage the surface of the ice beneath the runners and causethe apparatus to be moved back and forth, according to the direction ofrotation of the spur wheel. The depression of the foot tread W willserve to raise the marking blades from the ice.
